Are single fractions of radiotherapy suitable for plantar fasciitis?

The use of radiotherapy for plantar fasciitis has never been reported in Australasia and is scarcely found in the English language medical literature, but it is commonly used in Europe, especially in Germany. In Europe, treatment courses consisting of multiple small fractions have been associated with high levels of pain relief. In the present report, the use of single fractions or radiotherapy was evaluated by reviewing seven consecutive patients referred for treatment and by applying objective and subjective criteria for pain relief. One patient died of unrelated causes soon after treatment and one declined to receive radiotherapy. Four patients each received a single dose of 8 Gy resulting in complete pain relief. One patient was treated with 8 Gy and 12 weeks later was retreated achieving partial pain relief. A follow‐up interview was conducted after a mean of 15.6 months, ranging from 1.5 to 30 months. No acute or late effects occurred; however, the possibility that delayed effects may yet occur, particularly carcinogenesis, cannot be excluded. Radiotherapy for this common condition should be investigated further as it might be safer and more effective than other methods currently in use.     

Feasibility of transperineal prostate biopsy under interventional magnetic resonance guidance

A patient, who was not suited for ultrasound-guided biopsy, was biopsied in an interventional magnetic resonance unit at Brigham and Women's Hospital. Real-time magnetic resonance imaging provided verification of placement before tissue samples were taken. This technique successfully sampled tissue from the prostate and led to a diagnosis of cancer.     

Randomised controlled trial of zinc supplementation in malnourished Bangladeshi children with acute diarrhoea

OBJECTIVE: To evaluate the impact of zinc supplementation on the clinical course, stool weight, duration of diarrhoea, changes in serum zinc, and body weight gain of children with acute diarrhoea. DESIGN: Randomised double blind controlled trial. Children were assigned to receive zinc (20 mg elemental zinc per day) containing multivitamins or control group (zinc-free multivitamins) daily in three divided doses for two weeks. SETTING: A diarrhoeal disease hospital in Dhaka, Bangladesh. PATIENTS: 111 children, 3 to 24 months old, below 76% median weight for age of the National Center for Health Statistics standard with acute diarrhoea. Children with severe infection and/or oedema were excluded. MAIN OUTCOME MEASURES: Total diarrhoeal stool output, duration of diarrhoea, rate of weight gain, and changes in serum zinc levels after supplementation. RESULTS: Stool output was 28% less and duration 14% shorter in the zinc supplemented group than placebo (p = 0.06). There were reductions in median total diarrhoeal stool output among zinc supplemented subjects who were shorter (less than 95% height for age), 239 v 326 g/kg (p < 0.04), and who had a lower initial serum zinc (< 14 mmol/l), 279 v 329 g/kg (p < 0.05); a shortening of mean time to recovery occurred (4.7 v 6.2 days, p < 0.04) in those with lower serum zinc. There was an increase in mean serum zinc in the zinc supplemented group (+2.4 v -0.3 mumol/l, p < 0.001) during two weeks of supplementation, and better mean weight gain (120 v 30 g, p < 0.03) at the time of discharge from hospital. CONCLUSIONS: Zinc supplementation is a simple, acceptable, and affordable strategy which should be considered in the management of acute diarrhoea and in prevention of growth faltering in children specially those who are malnourished.     

Dietary factors and the risk of squamous cell esophageal cancer among black and white men in the United States

Objectives: To investigate dietary factors for squamous cell esophageal cancer and whether these factors may contribute to the five-fold higher incidence of this cancer in the black versus white population of the United States.Methods: Data from a food frequency questionnaire were analyzed for 114 white men and 219 black men with squamous cell esophageal cancer, and 681 white and 557 black male controls from three areas of the United States who participated in a population-based case-control study of esophageal cancer.Results: Protective effects were associated with intake of raw fruits and vegetables (odds ratio for high versus low consumers=0.3 in both white and black men) and use of vitamin supplements (especially vitamin C; odds ratio for high versus low consumers=0.4 in both races), with the frequency of consumption of raw fruits and vegetables and vitamin supplements being greater for white than black controls. In addition, elevated risks were associated with high versus low intake of red meat (OR=2.7 for blacks and 1.5 for whites) and processed meat (OR=1.6 for blacks and 1.7 for whites), with the levels of consumption being greater for black than white controls.Conclusions: In the United States, these dietary factors may contribute in part to the much higher incidence of squamous cell esophageal cancer among black compared to white men.     

Initial multicenter experience with double nucleoside therapy for human immunodeficiency virus infection during pregnancy.

OBJECTIVE: To study maternal and neonatal effects of combination nucleoside analog therapy administered to human immunodeficiency virus (HIV)-infected pregnant women for maternal indications. METHODS: A multicenter, prospective observational study was undertaken at six perinatal centers in the United States and Canada that supported regional referral programs for the treatment of HIV-infected pregnant women. Demographic, laboratory, and pregnancy outcome data were collected for 39 women whose antiretroviral treatment regimens were expanded to include more than one nucleoside analog for maternal indications. The 40 newborns were monitored at pediatric referral centers through at least three months of age to ascertain their HIV infection status. RESULTS: For all 39 women, zidovudine (ZDV) therapy was instituted at 13.4 +/- 8.2 weeks, with a second agent (lamivudine [3TC] in 85% of cases) being added at a mean gestational age of 17.6 weeks. Duration of therapy with two agents was 20.6 +/- 10.4 weeks overall, with no women stopping medications because of side effects or toxicity. No significant changes in maternal laboratory values were seen, except for an increase in mean corpuscular volume, over the course of pregnancy. No clinically significant adverse neonatal outcomes were noted, with all but the three preterm newborns leaving hospital with their mothers. Neonatal anemia (hematocrit < 50%) was seen in 62% of newborns, with no children needing transfusion; mild elevations of liver function tests, primarily aspartate aminotransferase, were noted in 58% of newborns tested, though none were clinically jaundiced. Overall rate of neonatal HIV infection was 2.5% (95% confidence interval: 0.1-13.2%). CONCLUSION: Combination antiretroviral therapy during pregnancy with two nucleoside analogs was well-tolerated by mothers and newborns, with no significant short-term toxicities or side effects noted. Surveillance of exposed newborns' hematologic and liver function appears warranted.     

Measuring clients' satisfaction with self-help agencies

OBJECTIVE: Clients' satisfaction with their involvement in treatment decisions has been largely overlooked in the formulation of satisfaction measures. The authors describe the development of a scale that assesses clients' satisfaction with services and with their involvement in treatment decisions. METHODS: Long-term users of four client-operated mental health self-help agencies were interviewed at baseline (N=310) and six months (N=248) using the 11-item Self-Help Agency Satisfaction Scale (SHASS). The scale was developed on the basis of consumers' input about their satisfaction with services and their involvement in treatment decisions. To explore the relationship between satisfaction as measured by the SHASS and outcomes, the six-month interview included four outcome measures-independent and assisted social functioning, symptom severity, and a sense of personal empowerment. Internal consistency, stability, and discriminant validity were evaluated. RESULTS: Factor analyses confirmed that the SHASS has two subscales, one assessing service satisfaction and the other assessing satisfaction with involvement in treatment decisions. The scale and its subscales showed high internal consistency, moderate stability, and discriminant validity. The SHASS subscales showed modest associations with two of four outcome measures-assisted and independent social functioning. CONCLUSIONS: The SHASS is a brief instrument that can be used to measure clients' satisfaction with their involvement in treatment in mental health self-help agencies.
